Functions --------- .. function:: localtime([secs]) Convert a time expressed in seconds since Jan 1, 2000 into an 8-tuple which contains: (year, month, mday, hour, minute, second, weekday, yearday) If secs is not provided or None, then the current time from the RTC is used. year includes the century (for example 2014). * month is 1-12 * mday is 1-31 * hour is 0-23 * minute is 0-59 * second is 0-59 * weekday is 0-6 for Mon-Sun * yearday is 1-366 .. function:: mktime() This is inverse function of localtime. It's argument is a full 8-tuple which expresses a time as per localtime. It returns an integer which is the number of seconds since Jan 1, 2000. .. only:: port_pyboard .. function:: sleep(seconds) Sleep for the given number of seconds. Seconds can be a floating-point number to sleep for a fractional number of seconds. .. only:: port_esp8266 or port_wipy .. function:: sleep(seconds) Sleep for the given number of seconds. .. only:: port_wipy .. function:: sleep_ms(ms) Delay for given number of milliseconds, should be positive or 0. .. function:: sleep_us(us) Delay for given number of microseconds, should be positive or 0 .. function:: ticks_ms() Returns an increasing millisecond counter with arbitrary reference point, that wraps after some (unspecified) value. The value should be treated as opaque, suitable for use only with ticks_diff(). .. function:: ticks_us() Just like ``ticks_ms`` above, but in microseconds. .. function:: ticks_cpu() Similar to ``ticks_ms`` and ``ticks_us``, but with higher resolution (usually CPU clocks). .. function:: ticks_diff(old, new) Measure period between consecutive calls to ticks_ms(), ticks_us(), or ticks_cpu(). The value returned by these functions may wrap around at any time, so directly subtracting them is not supported. ticks_diff() should be used instead. "old" value should actually precede "new" value in time, or result is undefined. This function should not be used to measure arbitrarily long periods of time (because ticks_*() functions wrap around and usually would have short period). The expected usage pattern is implementing event polling with timeout:: # Wait for GPIO pin to be asserted, but at most 500us start = time.ticks_us() while pin.value() == 0: if time.ticks_diff(start, time.ticks_us()) > 500: raise TimeoutError .. function:: time() Returns the number of seconds, as an integer, since 1/1/2000. @ 1.1 log @Initial revision @ text @@ 1.1.1.1 log @Import micropython version 1.5.2 into othersrc. Micropython is a python3 implementation that has been optimised for micro-controllers and small embedded systems. It also has a "unix" port. It has an MIT license. This is version 1.5.2 of micropython. MicroPython implements the entire Python 3.4 syntax (including exceptions, "with", "yield from", etc.). The following core datatypes are provided: str (including basic Unicode support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array, collections.namedtuple, classes and instances. Builtin modules include sys, time, and struct. Note that only subset of Python 3.4 functionality implemented for the data types and modules. This is the standard micropython source (version v1.5.2), which has been adapted to use reachover infrastructure. At the present time, libffi (from pkgsrc) is used. Alternative locations for libffi can be set using the PKGSRC_PREFIX definition to make. In the whole scheme of things, micropython is quite small: % size bin/micropython text data bss dec hex filename 393495 1624 2208 397327 6100f bin/micropython % and runs much as expected: % bin/micropython MicroPython v1.5.2 on 2016-01-13; linux version Use Ctrl-D to exit, Ctrl-E for paste mode >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> % python2.7 Python 2.7.10 (default, Oct 17 2015, 17:55:29) [GCC 4.8.5] on netbsd7 Type "help", "copyright", "credits" or "license" for more information. >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> ^D % This (reachover) version runs all the tests which the gmake version does. % make t cd bin && make t cd /home/agc/local/micropython/bin/../dist/unix/../tests && env MICROPY_MICROPYTHON=/home/agc/local/micropython/bin/micropython ./run-tests pass basics/0prelim.py pass basics/andor.py pass basics/array1.py pass basics/array_add.py pass basics/array_construct.py pass basics/array_construct2.py ... pass unix/ffi_callback.py pass unix/ffi_float.py pass unix/ffi_float2.py 474 tests performed (15812 individual testcases) 474 tests passed 5 tests skipped: cmd_showbc cmd_verbose machine1 machine_mem extra_coverage % The sources are available from github: https://github.com/micropython/micropython micropython release at: https://github.com/micropython/micropython/releases Sources for 1.5.2 taken from: https://github.com/micropython/micropython/archive/v1.5.2.tar.gz Alistair Crooks agc@@netbsd.org Wed Jan 13 17:15:30 PST 2016 @ text @@
